Answer:

A. 71% (±18%)

Step-by-step explanation:

Based on the confidence interval relation :

Mean ± Margin of error

The mean could be any given value :

However, the margin of error at a given confis nce level will will affected by the sample size, larger sample sizes will result in smaller margin of error values as the it will result in a large value denominator hence giving a small margin if error value when divided.

Margin of Error = Zcritical * σ/√n

Since.weve been told that the sample size is small, this will result in a large error margin value, from the options given, the value with the largest error margin value will be produced by the smallest samole size. Hence the option with the largest error margin value is ; ±18%

Draw a regular pentagon so that it has a perimeter of 20 cm. Use the Regular Polygon Area Conjecture and a centimeter tyler to f

Ratling [72]

Answer:

Check the graph below. $Area = 27.52 cm^{2}$

Step-by-step explanation:

A Regular Pentagon has an interior angle of 108º an an exterior angle of 72º.

Since the perimeter is 20 cm, let's draw it respecting it those properties, besides all of the three sides must have the same measure.

And since we can divide it, into three triangles, we can calculate the area using tangent.

So, let's find out the area:

$A_5=\frac{s^{2}n}{4tan(\frac{180}{n})} =\frac{4^{2}*5}{4tan\frac{180}{5}}\\ \\A\approx27.52cm^{2}$

So check it down
